LOOSE-LEAF BINDER.

Application filed July 19,

' To all whom it may concern:

Be it known that I, Connors L. HARVEY, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Loose- Leaf Binders,of which the 'following is a fuIL-clear, and exact description, such as v .will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whi ch- 1 Figure .1 is a plan view of my improved loose leaf binder.

F ig. 2 is an enlarged vertical sectional view on the line 2-2 of Fig. 1.

Fig. 3. is a plan view of the locking bar.

Fig. 4 is an enlarged cross-sectional View on the line 4-4: of Fig. 3.

Fig. 5 is a'detail view of parts of the extensible post.

Fig. 6 is a detail view of the ram member which. moves the locking bar.

Fig. 7 is a detail view showing my extensible post used in connection with a supple mental post section.

This invention relates to a new and useful improvement loose-leaf. binders, the object being to construct 'a'binder oi the charaoter-described which will be cheap, easilyoperated, and effective, particularly when employed in connection with an improved form of rack, forming the subject-matter of a companion application filed'by me of even dateherewith.

In the drawings, 1 indicates the top cover, to which is hingedly connected asplit or divided back frame bar 21 This bar 2 is composed of two sections 3 and 4 connected together by, screws 5, the former section having a longitudinally disposed groove in its lower face in which looking bar 6 is slid- -ingly arranged. Bar 6 is formed with a keyhole opening 6 at each. end, and at about its center is provided with a trans versely disposed slot 6". ,7' indicates a disk seated in a socket'in section 31 (above; the bar 6) and'having a crank-pin8 operating in the slot 6,whereby upon a half turn being imparted to the disk, the locking bar is moved longitudinally a distance equal to the throw of the crank pin, the osition of the bar at'the left, as shownin igs. 2 and 3,

being its locked position twherein the .nar-

row portions of the keyhole openings engage under the heads of the posts, hereinafterde- Specification of Letters Patent. Patented J 1111? 26, 1921.

forming a head portion 10, under which the edge of the .keyhole openings is moved when the locking bar is operated to lock the top cover 1n position, as shown in Fig. 2.

10 indicates an inwardly extending flange forming a bearing near the upper end of the sleeve 10, which bearing provides a support for the head of a threaded rod 11 whose upper end is squared, as at 11, to receive a key through an opening 3 in the plate 3 by which the rod 11 may be rotated. In order to hold the rod 11 in position against the bearing 10, I introduce a washer 12 through the upperend of the bore of the sleeve, and by a driving fit force the same down close to the head portion of the threaded rod 11, whereby sald rod may be freely rotated but is prevented from longitudinal displacement relative to the sleeve.

13 indicates a female member of the extensible post having an opening to receive the rod 11, said post 13 fitting snugly within the sleeve 10, but permitting freedom Jof movement of sleeve 10 thereon. The lower end ot'post l3'is provided with a non-circular shank portion 13 below which at head portion 13 13? indicates a nut having a threaded .opening for cooperating with the rod 11, and which nut is provided with a threaded stem screwed into the upper end of-post 13. When it is desired to introduce a' supplemental post section 13 in position to extend the-post beyond the limits of the adjustment of the-rod 11, this nut 13 is removed from the upper end of post 13. The extra post section 13 is then screwed into the top of post 13, and finally the nut 13 is screwed into the upper end of the supplemental post section'13 ,.as shown in Fig. 7. '1

This method of extending or building up posts, I-believe, is well known in the art.

14 indicates a screw whose, head portion is accessible from the exterior, and which screw, when turned in against the non-01rcular shank 13 locks the post 13 in position and at the same time prevents rotation thereof. When the screw 14 is turnedout sufliciently far, the post 13 and its associated parts may be entirely removed. When the post 13 is locked in position in the bar 15,

which constitutes the lower backing plate to which the lower cover 16 is hingedly connected, as shown in Fig. 1, the rotation of the threaded rod 11, say, in an anticlockwise direction will cause the sleeve to be raised relative to the post. 13, thus extending the post and permitting introduction of new leaves into the volume. These leaves are indicated by dotted lines 17in Fig. 1 and have notches '17 at their four corners by which they engage the extensible post, thesenotches permitting the leaves to be inserted and removed at will into and from any portion of the volume without necessitating the removal' or displacement of the other leaves,

' except, of course, to ofl'e'rsufiicient space for the introduction of a new leaf or s'uflicient clearance for the removal of an old leaf.

There are two extensible posts connecting the backing plates of the cover, and both of" these posts are preferably of similar construction' and interchangeable, being removably mounted in the bottom backing plate as .3 above described. I shall not describe in detail the second extensible post, indicated at 18 as an entirety, as the same, as just stated, may be similar in construction to the extensible and removable post hereinbefore described.

-What I claim is:

1. A loose leaf binder consisting of two backing plates, at removable post composed of telescoping sections, one of which is mounted in one of said backing plates, said section at its point of mounting in said .plate having a non-circular shank portion and a head, and a set screw in the backing plate for engaging said non-circular shank portion.

- 2. A loose leaf binder consisting of two backing plates, an extensible post comprising telescopic sections, oneof which is seated in one of said backing plates, a set-screw for holding said post-section .in position, on said plate, a locking bar on the other of said backing plates for engaging a head on the other of said post sections, said two-post sections being connected together by a rod having threaded engagement with one of said post-sections, and a rotatable engagement with the other.

' 3. A loose leaf binder consisting of two backing plates, one of which has a seat, a

post section in said seat, means for locking sald post sectlon in its seat, said post section being tubular at one end, a nut secured insaid tubular end, a telescoping complementary post section having a head on its outer end, means on the other of said backing plates for engaging said head, and a threaded rod mounted for rotation in the last mentioned post section, said rod engaging said nut,'and means for holding said rod against longitudinal movement relative to the post section in which it is mounted.

In testimony whereof I hereunto aflix my 1 day of Jul 1920.
